Embodiment 1

[0042] This example is a preparation example of a water / oxygen barrier polymer-based composite film material.

[0043] The water / oxygen barrier polymer matrix composite film material is prepared according to the following steps:

[0044] 1. Prepare the prepolymer of the upper layer and the lower polymer surface layer: get 0.8049g (4.02mmol) of diamine monomer diaminodiphenyl ether ODA and add it in 10mL DMF solution, and continue to stir for a period of time to make the system fully mixed; In the above system, add 0.8943 g (4.10 mmol) of dianhydride monomer 1,2,4,5-pyromellitic dianhydride PMDA was added and stirred at a moderate speed for 6 hours until the system formed a sol.

[0045] 2. Modification and intercalation of inorganic layered fillers: take 10 g of sodium-based montmorillonite and 100 mL of ultrapure water to make a 5%-10% suspension under the condition of ultrasonic stirring. The upper suspension was centrifuged to obtain montmorillonite with smaller particle s...

Abstract

The invention discloses a water / oxygen barrier polymer-based composite material. The water / oxygen barrier polymer-based composite material is formed by enabling inorganic matter layered filler to react with a surface modification agent and an intercalation agent and dispersing reaction products into a polymer base material, wherein the polymer base material is an organic polymer which contains an amido bond, hydroxyl or carboxyl. The water / oxygen barrier polymer-based composite material has the advantages that a water / oxygen barrier layer is simple in structure and effective; a preparation method of the composite material is a solution-state production process, and a vacuum process is not involved in the preparation process, so that the preparation method is simple; the water / oxygen barrier polymer-based composite material is low in preparation cost and wide in application scope.

Description

technical field [0001] The present invention relates to the field of flexible electronics and display devices. Background technique [0002] With the rapid development of science and technology, the application of packaging materials with barrier properties has rapidly expanded from the field of traditional food and drug packaging to the field of electronic product packaging. Various high-tech electronic products have more and more stringent requirements for the barrier properties of packaging materials. The requirements for water and oxygen barrier properties in different fields are as follows: [0003] Table 1. Demand range for barrier properties of packaging materials in different fields [0004] [0005] In the field of organic electroluminescent devices (OLEDs), the barrier properties of packaging materials are particularly demanding. Organic Light-Emitting Diodes, also known as Organic Light-Emitting Diodes (OLEDs), were discovered in the laboratory by Chinese-Ame...
